Diagnosing landscape plant problems can be challenging. However, an assessment of the entire growing site may aid in the diagnostic process. This publication was designed to provide a starting point for determining possible causes behind various plant problems. The step-by-step guide directs the user through the diagnostic process of observation and information gathering. Possible causes are suggested as part of the list of symptoms. Should the field site diagnosis be inconclusive and samples need to be submitted to one of the University of Kentucky Plant Diagnostic Laboratories, the information gathered with the help of this publication can provide valuable supplementary information.
Considerations for Diagnosis of Ornamentals in the Landscape (PPFS-GEN-15) is available online.
